MILK-COOLER.

SPECIFICATION forming part of Letters Patent No. 630,835, dated August15, 1899.

Application filed November 4, 1895. Serial No. 567,867. (No model.)

To @ZZ whom it may concern..-

Be it known that I, JOHN Q. ADAMS, Jr., a citizen of the United States,residing at Lawn Ridge, in the county of Scotland and State oflNIissouri, have invented a new and useful Combined Milk-Cooler andRefrigerator, of which the following is a specification.

My invention relates to a milk-cooler and refrigerator designed tosecure an eficient circulation of air and ventilation of the contents ofthe milkreceptacles and at the same time provide easy access to thevarious parts of the apparatus to facilitate cleansing.

A special object of my invention is to provide a compact arrangement ofice-box and milk-receptacles in a casing adapted for storage purposeswhereby the circulation of air desirable in order to ventilate thecontents of the milk-receptacles can be utilized also for carrying oodors emanating from vegetables or meats in the storage-compartmentwithout aecting the contents of the milk-receptacles, the position ofthe ice-box withinthe casing being controlled to allow inspection of thecontents of the lmilk-receptacles by the spigots which serve to withdrawsaid contents.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure l is a perspective View of a milk-cooling andrefrigerating apparatus constructed in accordance with my invention.Fig. 2 is a longitudinal section of the same, taken centrally. Fig. 3 isa horizontal section on the line a: Q0 of Fig. 2. Fig. 4 is a transversevertical section on the line y y of Fig. 3. Fig. 5 is a detail view inperspective of the ventilator. Fig. 6 is a similar View of theadjustable member of the ventilator detached.

Similar numerals of reference indicate corresponding parts in all theiigu res of the drawings.

In the casing l, which is double-walled to form an intervening dead-airspace adapted to contain aheat-non-conducting medium,are arrangedtransverse supporting-bars 4, below which is a storage-compartment 16,accessible by means of doors 18 and provided with suitable shelves 17 orthe equivalents thereof.

The casing is closed at its topv by a lid or cover 2, which is also ofdouble-walled con= struction and of which the inner'wall is offset toextend downwardly intothe casing or between the side and end wallslthereof and break joint.

Located within the casing and approximately coextensive with theinterior thereof is an ice-box 3, supported by the bars 4, said box,however, being of an area sufficiently less than the interior of thecasing to arrange its side andend walls respectively out of contact withthe adjacent walls of the casing. For convenience, however, the frontwall of the ice-box is arranged close to the inner surface of thecorresponding wall of the casing, but is held out of contact therewithby forwardly-projecting portions of the ice-box respectively contiguousto an inspection-pane 9 and outlets which are in communication with theinterior of the box. These projections abut against the inner surface ofthe front wall of the casing to limit the forward movement of theice-box upon the supporting-bars 4. and form a narrow space between saidwalls to allow a circulation of air.

Arranged within the ice-box are milk-receptacles 6, disposed-atintervals and having their front end walls secured to and in contactwith the front wall of the ice-box, while the top, bottom, side walls,and remaining end wall are spaced from the adjacent walls of the ice-boxto allow contact therewith of the refrigerating contents of said box,iceracks 7 being disposed between adjacent receptacles to support ice ata point above the plane of the bottom of theboX. These milkl receptaclesare provided with snugly-fitting covers 8, having Ventilating-openingsprovided with interstitial or reticulated guards S, and the tops of thereceptacles Gare flush with the upper edges of the walls of the iceboxand also are spaced slightly from the plane of the under surface of thecasing lid or cover 2 toallow circulation of air over the top of theice-box to communicate with a ventilator which is located centrally ofthe lid or cover. This ventilator in the construction illustratedconsists of a fixed tube 19, eX- tending vertically through the innerand outer Walls of the cover and communicating with the interior of thecasing, said tube being IOO provided with Ventilating-openings 24 and acap 23, removablymounted to close the up per end of said tube 19 andprovided with a tubular collar 22, which is crimped or reduced at itslower end, as shown at 50, to fit snugly and rmly in the bore of thetube 19, said collar 22 being provided with ventilating-open-ings 20,adapted f or registration with the openings 24 of the tube 19 and alsoadapted by the turning of the cap to be arranged out of registrationwith said openings, and thereby close the same. Between the body portionof the cap and the upper end of the tubular collar 22 in theconstruction illustrated is a small space which I desire to remainpermanently open, whereby even with the Ventilating-openings 2O 24closed there will be sufficient circulation of air through the casing tocarry olf the fumes of the contents thereof. Obviously a greater extentof ventilation may be attained by arranging the parts of the ventilatorto register the openings 20 and 24.-, or, in case of necessity, the capmay be entirely removed to allow free vent for the vaporous contents ofthe receptacles. The crimping of the lower end of the tubular collar 22enables me to force said collar snnglyinto the bore of the stationarytube 19 to secure the adjustable cap in place at the desired adjustment,whereby the ventilatingopenings 2O 24 may be either wholly or partlyalined or may be wholly non-alined.

The above-mentioned inspection-panes 9 are arranged to give a view ofthe contents of the milk-receptacles 6, said panes being arrangedopposite registering slots formed, respectively, in the front walls ofthe iceboX and receptacles, and alined, respectively, with saidinspection-panes are corresponding panes 10, let into the wall of thecasing, whereby the depth of liquid in either of the receptacles can beascertained from the exterior of the casing.

' The ice box or tank is held in its proper position in the casing bymeans of spigots 12 and 14, of which the former communicates withoutlets of the milk-receptacles 6, while the latter communicates with anoutlet of the ice-box, said spigots extending through the inner andouter walls of the casing and being threaded into suitable seats formedin said outlets. As hereinbefore indicated, the projecting portions ofthe outlets bear against the inner surface of the inner wall of thecasing to space the front wall of the ice-box from that of the casing;also, I preferably provide the milk-receptacles and the ice-box incommunication with their outlets with depressed chutes 11 and 13 tofacilitate the removal of all of the liquid contents of said receptacleand ice-box, the chutes serving to collect the liquid at points near theoutlet.

From the foregoing description it will be seen that the removableice-box in which the milk-receptacles are fixed is approximatelycoeXtensive with the interior of the casing, but is spaced at its sideand end walls from the corresponding walls of the casing to formpassages through which a circulation of air is afforded, the narrowspace 15 between the' front wall of the tank andthe wall of the casingbeing sufcient to allow an upward current of heated air or a downwardcommunication of chilled air, and that by the removal of the spigots,which normally hold the ice-box in its proper position, the latter isreleased for removal. Furthermore, it will be seen that themilk-receptacles and the con taining icebox are arranged at the top ofthe interior of the casing to leave an unobstructed storagechambertherebelow; but the upper edges of the walls of the ice-box, with whichthe tops of the milk-receptacles are Hush, are spaced downwardly fromthe plane of the under surface of the lid or cover sufficiently to allowa circulation of air thereover in order =to reach the outlet formed bythe ventilator, and this current of air passing horizontally over theperforated tops of the milk-receptacles serves to ventilate the latterby exhaustion, whereby the odors emanating from the contents of thestorage-compartment are not communicated to the contents of themilk-receptacles.

The eiiiciency of the above-described apparatus depends to a materialextent upon the fact that the vertical passages between the walls of theice-box and the walls of the ca sing communicate with a Hat horizontalpassage located above the plane of the upper edges of the walls of theice-box and between the same and the under fiat surface of thel IOO 1nunicatin g with the ventilator, and also upon the fact that theupperflat perforated covers of the milk-receptacles are locatedin the.

.tion thereof to remove fumes is produced.

Alsoit will be seen that'the upper iiat horizontal lids or covers of themilk-receptacles practically form the lower wall of the said horizontalpassage, of which the upper wall is formed by the under surface of thelid or cover of the casing, and as each of the milkreceptacles islocated 'between the vertical planes of the central ventilator and oneof the upright walls of the ice-box 'itwil1 be seen that any air risingbetween the walls of the ice-box and those' of the casing, and thus en-IIO tering the horizontal passage on its way to the ventilator, mustpass across the perforatedl top of one ormore of themilk-receptacles,and

. thus assist in ventilatin g the contents of those receptacles. A

Another advantage of the above-described vconstruction resides in thefact that the position of the ice-box in the casing is controlled by thespigots which are utilized to withdraw the liquid contents of thereceptacles and icebox, and as these spigots are exposed at the front ofthe casing any disarrangement of the ice-box, such as the backwarddisplacement thereof, may be corrected by grasping the spigots anddrawing said ice-box forward un- Itil its motion is checked by thecontact of the projections on the front wall of the ice-box with theinner surface of the front wall of the casing to arrange theinspection-panes of the ice-box close to and in alinemcnt with theinspectionspanes of the casing to enable the contents of themilk-receptacles to be viewed without opening the casing or otherwiseeX- posing the contents of the refrigerator.

Various changes in the form, proportion, and the minor details ofconstruction maybe resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

Having described my invention, what l claim isl. The herein-describedref'rigerating apparatus, having a casing and a horizontal lid or coyerprovided with a centrally-located ventilator, horizontal supporting-barsconnecting opposite walls of the casing, an opentopped ice-box removablyseated upon said supporting-bars with its side and end walls spaced fromthose of the casing, and its upper edge spaced from the undersurface ofthe lid or cover, to form a shallow horizontal passage connecting thespaces between the adjacent walls of the ice-box and casing with theventilator, milk-receptacles arranged in the ice-box and provided withhorizontal perforated lids or covers, flush with the upper edges of theice-box and forming the lower wall of the said horizontalpassage-between the upper edges ofthe ice-box and the plane of the coverof the casing, each of said milkreceptacles being arranged between thevertical planes of the ventilator and one of the said walls of theice-box, to provide for the horizontal passage thereover of a current ofair approaching the ventilator, alined inspec tion-panes in adjacentwalls oftheice-box and casing, to allow a view of the contents of themilk-receptacles, and spigots movably eX- tcnding through the wall ofthe casing and connected with the ice-box, in communication with thesame and the milk-receptacles, respectively, to maintain the ice-boxwith said inspection-panes in alinement, substantially as specied.

2. The herein-described refrigerating apparatus, having a casing and aflat lid or cover provided with a ventilator, horizontal supporting-barsarranged in the casing, an opentopped ice-box seated upon said bars withits side and end walls spaced from those of the casing and its upperedge spaced from the under surface of the lid or cover, said iceboXbeing provided in its front wall with inspection-panes and adjacentexterior spacing projections for contact with the front wall of thecasing, to limit the forward movement of the ice-box, correspondinginspection-panes in the wall of the casing for alinement with those inthe ice-box, milk-receptacles arranged in the ice-box and provided withhorizontal perforated lids or covers ush with the upper edge of theice-box, said receptacles being located between the vertical plane ofthe ventilator and one of the walls of the iceboX, and interiorlyvisible through said inspection-panes in the wall of the ice-box, andspigots movably extending through the front wall of the casing, andconnected with the ice-box in communication, respectively, with theinteriors of the receptacles and ice-box, to maintain the latter withits inspectionpanes in alinement with those of the casing, and enablethe box to be advanced toward the front wall of the casing until checkedby said projections, substantially as specified.

In testimony that l claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
